SAP Ajax question

典

Is it possible to use ajax in SAP development?

For example, when open a customer page in SAP, can we read some data from other systems? ---Like ajax call service/ashx

Our SAP developer doesn't know ajax, is not able to answer my question...Funny

SAP is backend,

ajax is front end

you can expose all SAP API via webservices.

your front to mid tier just talking to those services.  so yes you can sure use ajax.

ask your sap grandpa and grandmas to enable them as webservices.

What I mean "SAP" is "Existing SAP UI"....I want SAP UI to consume ajax content.

What they have done is: added links to the SAP UI, so the user can click the button to open another window. Now users are complaining...I think the better way is to use Ajax...But the SAP developer didn't know about ajax...

哦， 你是倒過來用啊。

ajax content 怎麼能consume. ajax是post到webservice的。

你sap要consume，也得consume webservice 的content。
of course you can't use ajax in SAP dev environment, SAP use abap.

webservice 是直接跟SAP API 打交道的。 可以把"content" 直接post 到SAP 的 API。

所以answer is still yes, you can post content form web UI to internal SAP APIs

Yes, 倒過來用
I do see a lot of discussion about "SAP UI Ajax" on google, but don't understand what they are talking about...

ajax 是javascript, web 用的。 abap 怎麼能用？

我的理解是你的abap 程序想去call 一個 webservice 來讀取數據？

Yes, the SAP user needs to see some information which is not in SAP system (doesn't need to be stored in SAP)

So what we really need is:
SAP UI ---Call Ajax ---> load web element (or html elements or html parts)

LZ说的SAP UI也许是Enterpirse Portal里的page吧，NetWeaver不全是ABAP stack，有JEE的，可以Ajax。

我的理解你说的其实是cross domain ajax call，禁止的。

popup window不受此限制。

post content form web UI to internal SAP APIs?或者，用servlet之类把想要的web content读到当前服务器，要在防火墙上打很多洞。

SAP web 是JSP 或者 BSP写的，Ajax没问题，关键就是这个cross domain issue

ajax返回一个动态的js就行了，可以绕过跨区域调用
